Biometric identification \u2014 using unique physical attributes such as fingerprints to authenticate people \u2014 has been considered secure for a long time. As such, the technology is very appealing to banks and bank users, which together make up a gigantic target for cybercriminals.<\/p>\n
In fact, many banks are already testing new ATMs with biometric access \u2014 or have plans to do so soon.<\/p>\n
On the institutional side, the great advantage of such methods as iris scanning or vein matching<\/a> is that they decrease false reject (type I<\/a>) and false accept (type II<\/a>) rate errors. Users like biometrics because the technology works fast and frees them from dealing with passwords and other secret codes.<\/p>\n Unfortunately, fingerprint-scanning technology is both massively widespread and not as reliable<\/a> as it should be. For example, users of both iOS and Android devices regularly complain that their gadgets refuse to unlock for authorized users \u2014 or that they let in other people.<\/p>\n
